Obesity, Poor Diet, and Lack of Exercise Linked to Early Onset of Cancer



A top health expert from the University of Sydney, Australia, highlights the connection between lifestyle factors and the increasing incidence of cancer, particularly among younger individuals.

The Rise of Early Onset Cancer

  • Traditionally, cancer was associated with older age groups, but recent decades have witnessed a surge in cases occurring before the age of 40 or 50.
  • Studies show a significant increase in the rates of gallbladder, uterine, colorectal, kidney, and pancreatic cancers among individuals aged 30 to 39.

Causes of Early Onset Cancer

  • Unhealthy lifestyle choices, including obesity, poor dietary habits, and lack of physical activity, are primary contributors to the rise in cancer cases.
  • High consumption of sugary, salty, and fatty junk food combined with sedentary behavior is a major concern.

Who is at Risk?

  • Men are at a higher risk of developing cancer compared to women, and they are also more likely to succumb to the disease.
  • Incidence varies by gender and organ type, with prostate, lung, and colorectal cancers being prevalent among males, and breast, lung, and colorectal cancers predominant among females.

Commonly Occurring Early Cancers and Prevention Strategies

  • Early detection significantly improves the chances of curing certain cancers, such as cervical and colorectal cancers.
  • Prevention is key, with vaccination being effective against cervical cancer, which is primarily caused by specific strains of the human papillomavirus (HPV).
  • National screening programs for breast, cervical, and colorectal cancers can aid in early detection and reduce mortality rates.
  • Age-based screening programs may not be sufficient, and there’s a need for personalized screening based on individual risk factors.
  • Modern technologies like genomics, big data, and artificial intelligence (AI) hold promise in developing personalized screening programs.


Understanding the link between lifestyle choices and cancer risk is crucial in combating the increasing incidence of early onset cancer. Emphasizing healthy habits and implementing targeted screening programs can make a significant difference in reducing the burden of the disease.
